Field of the Invention The present invention relates to an illumination lamp, and more particularly to an illumination lamp using a light-emitting diode (hereinafter referred to as "LED") as a light source. [Previous technology] In order to comply with the @ rationalization law (hereinafter referred to as "energy saving method") that promotes the use of energy to prevent global warming, in recent years, various aspects have been adopted in the field of lighting, for example, development of LEDs as An illumination lamp of a light source (see, for example, Patent Document 1). Since the LED is used as a light source, the power consumption is extremely small, and the life is long, and the luminance can be easily controlled by the current, and the speed is fast and the light is stable. Therefore, it is attracting attention as a new type of illumination instead of a white hot electric ball. . The illuminating lamp using the LED as a light source includes: a light source composed of a plurality of LEDs; an LED mounting substrate on which a plurality of LEDs are mounted; and an outer casing for mounting an LED mounting substrate on which a plurality of LEDs are mounted. Further, in the casing, an opening portion is formed on a side where the plurality of LEDs are located, and the opening portion is covered by the transparent protective cover so that the outside air does not enter the inside of the casing. ° Further, the LED is used as a light source In the illuminating lamp, heat is generated when the LED emits light, so that the outer casing has a heat dissipating effect (for example, refer to Patent Document 2 and Patent Document 3). In the LED lighting device of Patent Document 2, the LED mounting substrate is fixed to the bottom of the casing via a heat dissipating fixing plate, and a plurality of fins embedded in the bottom of the casing are formed in the heat dissipating fixing plate. Further, in the heat dissipation structure of the street lamp using the high-power LED, the outer casing is composed of the upper cover and the lower cover, and the LED mounting substrate and the protective cover are attached to the lower cover, and the heat sink is formed on the outer periphery of the upper cover. . [Patent Document 1] JP-A-2001-256805 [Patent Document 2] JP-A-2002-299700 (Patent Document 3) Japanese Patent No. 3127938. [Summary of the Invention] @ [Invented Problem] However, in the LED lighting device described in the prior art and the heat dissipation structure of the street lamp using the high-power LED, the heat from the LEDs can be dissipated by the heat dissipation fins or the heat sink, but the outer casing is sealed. Therefore, the heat from each LED convects inside the casing, and cannot effectively dissipate heat to the outside. The present invention has been developed in order to solve the above problems,

其目的在於提供，能夠有效率地將因複數個LED發光所 U 產生的熱能予以散熱之照明燈。 [用以解決課題之手段] - 爲了達到上述目的，本發明的照明燈係具備有：將 LED作爲光源之複數個投光器被固定成平面狀，且使光透 過之保護蓋以覆蓋複數個投光器的方式被固定於一方的板 面之安裝基板；用來將在複數個投光器所產生的熱予以散 熱，而在從安裝基板的另一方的板面突出的狀態下被固定 -6- 200944710 之複數個板狀冷卻鰭片；及具有收納凹部，且將安裝基板 固定成複數個板狀冷卻鰭片位於該收納凹部內、及保護蓋 位於該收納凹部的開口面側之殼體，安裝基板係形成爲在 與殼體之內周壁之間產生取入外氣用空間，複數個板狀冷 卻鰭片係形成爲突出於取入外氣用空間上並藉由從該取入 外氣用空間進入的外氣所冷卻，並且殼體設有複數個隙縫 ，該縫隙係將從取入外氣用空間進入並受到複數個板狀冷 Φ 卻鰭片的散熱作用所加溫過的前述外氣釋放到外部。 依據此第1形態之照明燈，由於當複數個投光器發光 ，其熱經由安裝基板傳達到複數個板狀冷卻鰭片時，因該 複數個板狀冷卻鰭片所放散的熱，產生熱上昇氣流，從取 入外氣用空間吸入外氣，進一步該被吸入的外氣通過複數 個板狀冷卻鰭片間之狹窄空間，故，藉由文土里效應，使 得熱上昇氣流速度加快，比起通常的環境狀態，更多量的 空氣通過複數個板狀冷卻鰭片間，因此可大幅地提昇冷卻 ❽ 效率。 本發明的第2形態係如第1形態之照明燈，其中，複 - 數個板狀冷卻鰭片的取入外氣用空間內之佔有面積爲鳥等 - 的動物無法從開口面進入到前述殼體之收納凹部內的大小 。因以往的照明燈爲密閉構造，鳥等的動物雖不會進入， 但在本發明的照明燈，因在安裝基板與殼體之開口端之間 形成有取入外氣用空間，所以，在本發明的第2形態，利 用複數個板狀冷卻鰭片突出於取入外氣用空間，能將該複 數個板狀冷卻鰭片的取入外氣用空間之佔有面積作成爲’ 200944710 鳥等的動物無法從開口面進入到殻體之收納凹部內。 本發明的第3形態係如第1形態或第2形態之照明燈 ，其中，安裝基板與板狀冷卻鰭片爲相同的導熱性材質。 依據這樣的第3形態之照明燈，因熱傳導率成爲相同，所 以熱傳達效率變好。 本發明的第4形態係如第1形態至第3形態中任一形 態之照明燈，其中，殼體、安裝基板及板狀冷卻鰭片，至 少該殼體以鎂合金形成。依據這樣的第4形態之照明燈， 因以熱傳導率高且輕量的金屬所形成，所以，有助於大幅 地提高冷卻效率，並且，變得容易設置照明燈。 本發明的第5的形態係第1形態至第4形態中任一形 態之照明燈，其中，將隙縫設置於殼體之位置係被因應 LED的照射方向藉由複數個板狀冷卻鰭片的散熱作用所加 溫的外氣上昇之方向所決定。依據這樣的第4形態之照明 燈，可有效率地使從複數個板狀冷卻鰭片所放散的熱釋放 到外部，因此可提高冷卻效率。 [發明效果] 若依據本發明的照明燈，因可將外氣有效率地導入到 燈具空間內，並且可將該外氣直接導引到板狀冷卻鰭片， 進一步朝隙縫釋放，所以，能夠將因複數個LED發光所 產生之熱能有效地擴散到外部。 【實施方式】 -8- 200944710 以下，參照圖面，說明關於用來實施本發明的照明燈 之最佳實施形態例。圖1係顯示本發明的照明燈1之最佳 的一實施形態之全體斜視圖。圖2係顯示從光源側觀看本 發明的照明燈1之狀態的正面圖。圖3係顯示從上面觀看 圖2的照明燈1之狀態的平面圖。圖4係顯示從左側面觀 看圖2的照明燈1之狀態的左側面圖。圖5係顯示從右側 面觀看圖2的照明燈1之狀態的右側面圖。圖6係顯示從 φ 下面觀看圖2的照明燈1之狀態的底面圖。圖7係顯示從 背面觀看圖2的照明燈1之狀態的背面圖。圖8係顯示圖 2之斷面XX的斷面圖。圖9係顯示圖2之斷面YY的斷 面圖。圖10係顯示圖7之斷面ZZ的斷面圖。再者，透 過關於照明燈1之圖面的全體，對相同要件賦予相同圖號 。又，在圖1中省略了投光器。又，在圖1、圖2，因保 護蓋3爲透明，所以使用實線來顯示投光器2。 本發明的照明燈1係如圖1〜圖9所示，具備有：將 ❹ LED作爲光源之複數個投光器2固定成平面狀，使光透過 之保護蓋3以覆蓋複數個投光器2的方式固定於一方的板 - 面4a之安裝基板4;用以使在複數個投光器2所產生的 - 熱予以散熱，而在從安裝基板4的另一方的板面4b突出 之狀態下被固定著的複數個板狀冷卻鰭片5;及具有收納 凹部6a，以複數個板狀冷卻鰭片5位於該收納凹部6a內 、及保護蓋3位於該收納凹部6a的開口面側之方式固定 安裝基板4之殼體6。這樣的照明燈1，其外形爲組合圓 錐台la、設置於圓錐台la的外徑大之側的圓柱lb所成 -9- 200944710 的形狀，成爲殼體6的開口面之開口端6b係形成爲圓形 。再者，投光器2係能夠藉由透鏡部將從LED所發光之 具定向性的光擴散，在圖中，64個呈年輪的方式排列成 圓形狀。 殼體6係照明燈1的外形，呈將中空的圓錐台1 a部 分、和設置於中空的圓錐台la部分的外徑大之側的中空 的略圓柱lb部分組合所成之形狀，開口端6b形成爲圓形 狀。在圓錐台la部分的外徑小之側，設有插座體61，該 插座體61係收納有用來對各投光器2供給預定的電力之 電源部並由有底圓筒構件所構成，其一部分從上壁6c突 出。在此插座體61的一部分突出之部位，固定有3字形 把手62。又，在殻體6的圓錐台la部分的周壁上，於全 體範圍穿孔設有複數個隙縫63.。且，在殼體6的開口端 6b之內周壁6d，如圖2、圖10所示，於直徑方向的線上 之2部位，設有用來固定安裝基板4之托架64、65。這 樣的殻體6係以例如鎂合金、鋁合金、銅等的熱傳導率高 之金屬來形成爲佳，但因照明燈1較輕量則變得容易設置 ，所以理想爲鎂合金來形成，特別是在大型的照明燈1之 情況，軽量化之容易設置度更爲顯著。 其次，根據圖11〜圖18，說明關於安裝有複數個投 光器2、保護蓋3及複數個板狀冷卻鰭片5之安裝基板4 〇 圖11〜圖18係顯示將本發明的照明燈的構成要件的 一部分之投光器2、保護蓋3及複數個板狀冷卻鰭片5安 200944710 裝於安裝基板4之狀態的圖。圖11係顯示從光源側観看 本發明的照明燈的情況時之安裝基板4的狀態之正面圖。 圖12係顯示從上面觀看本發明的照明燈的情況時之安裝 基板4的狀態之平面圖。圖13係顯示從左側面觀看本發 明的照明燈的情況時之安裝基板4的狀態之左側面圖。圖 -

As shown in FIG. 11 to FIG. 15, FIG. 17, and FIG. 18, the protective cover 3 is formed to cover a plurality of light projectors 2 along the outer circumference of the mounting substrate 4, and the outer portion is formed to be low by the step. The step portion 31 is fixed to one of the plate faces 4a by screwing or the like. The protective cover 3 is formed of, for example, a transparent synthetic resin such as polycarbonate or acrylic resin. Further, the step portion 31 of the protective cover 3 is covered by the edge cover 32 fixed to the mounting substrate 4. As shown in FIGS. 11 to 18 and FIGS. 1 and 2, a plurality of plate-shaped cooling fins 5 are formed so as to protrude from the space S for taking in the outside air, and enter the space S for taking in the outside air. The outside air is cooled. Specifically, the plate-like cooling fins 5 are formed in a rectangular shape, and their longitudinal directions are arranged in a direction orthogonal to the radial direction of the direction in which the mounting seats 4d and 4e of the mounting substrate 4 are formed. Further, a plurality of plate-shaped cooling fins 5 are arranged at equal intervals along the diameter direction of the mounting direction of the mounts 4d and 4e of the mounting substrate 4. The space between the plate-like cooling fins 5 is formed by a narrow space in which the effect of the soil is generated in the casing 6. For example, when the maximum diameter of the casing 6 is 430 mm and the length is 500 mm, the plate-shaped cooling fins 5 having a thickness of 1 mm can be arranged at intervals of 5 mm to produce a textual effect. By forming the interval between the plate-like cooling fins 5 as described above, the flow velocity of the gas passing through the plate-like cooling fins 5 can be increased. Both end portions of each of the plate-shaped cooling fins 5 are formed along the inner peripheral wall 6d of the slightly cylindrical portion lb portion of the casing 6, and the occupied area of the plurality of plate-shaped cooling fins taken into the outer air space S The animal such as a bird cannot enter the size of the housing recess 6a of the casing 6 from the opening surface. Since the conventional illuminating lamp has a hermetic structure, animals such as birds do not enter, but the illuminating lamp 1 of the present invention is formed between the mounting substrate 4 and the inner peripheral wall 6d -12-200944710 of the casing 6. Since the outer air space S is taken in, the plurality of plate-shaped cooling fins 5 are protruded from the outer air space S, and the plurality of plate-shaped cooling fins 5 can be taken into the outer air space S. An animal that has an area of a bird or the like cannot enter the housing recess 6a of the casing 6 from the opening surface. Such a plate-like cooling fin 5 is preferably made of the same thermal conductive material as the mounting substrate 4. Since the mounting substrate 4 and the plate-shaped cooling fins 5 are made of the same thermal conductive material, since the thermal conductivity is the same, the heat transfer efficiency is improved. For the purpose of the thermal conductivity of the mounting substrate 4 and the plate-like cooling fins 5, it is preferable to form a metal having a high thermal conductivity such as a magnesium alloy, an aluminum alloy, or copper, similarly to the casing 6, but the illumination is high. The lamp 1 is easier to set as it is lighter, so a magnesium alloy is preferred. Further, one of the mounting substrate 4 and the plate-shaped cooling fins 5 may be formed of a metal having a high thermal conductivity such as a magnesium alloy, an aluminum alloy or copper. The mounting substrate 4 on which the plurality of light projectors 2, the protective cover 3, and the plurality of plate-shaped cooling fins 5 are mounted is disposed in a column lb portion of the casing 6, and φ is disposed in the truncated cone la portion of the casing 6 with a socket body 61. . In the illumination lamp 1 in which the air flow path for the outside air flow from the intake air space S is taken in the casing 6, the description will be made regarding the illumination of the plurality of LEDs. The generated thermal energy diffuses to the external action. When a plurality of light projectors 2 are caused to emit light by lighting the illumination lamp, heat generated in each of the LEDs is transmitted to the plurality of plate-shaped cooling fins 5 via the mounting substrate 4, since the plurality of plate-shaped cooling fins 5 are removed from the plurality of plate-shaped cooling fins 5 The heat that is released generates a hot rising airflow, and the outside air is taken in from the space S for taking in the outside air. From -13 to 200944710, the inhaled outside air passes through a narrow space between the plurality of plate-like cooling fins 5, so that the flow rate of the hot ascending airflow is increased by the effect of the text, thereby forming a more normal environment. A large amount of air passes through a plurality of plate-like cooling fins 5. Further, the outside air that has entered the space for taking in the outside air and is heated by the heat dissipation of the plurality of plate-like cooling fins 5 is provided by a plurality of positions located above the plurality of plate-shaped cooling fins 5 The slit 63 is released to the outside. In this way, since the outside air can be efficiently introduced into the lamp space, and the outside air can be directly guided to the plate-like cooling fins 5, and further escaped to the slit 63, the cooling efficiency can be greatly improved. Therefore, it is ideally applied to high-power LEDs that generate a large amount of heat. Further, the illumination lamp 1 described above has an outer shape in which the truncated cone la and the cylinder lb provided on the outer side of the outer diameter of the truncated cone la are combined, and the open end 6b of the opening surface of the casing 6 is formed as The circular shape is not limited thereto, and as shown in FIG. 19 to FIG. 26, the illumination lamp having a shape of a truncated cone 1 00a and having an open surface formed in a rectangular shape may be used.

Figure 25 is a cross-sectional view showing a section XX of Figure 19. Figure 26 is a cross-sectional view showing a section YY of Figure 19. Furthermore, the same figure is given to the same element through the entire picture of the illumination lamp 1〇〇. Further, in Fig. 19, since the protective cover 300 is transparent, the light projector 200 is displayed using a solid line. As shown in FIG. 19 to FIG. 26, the illumination lamp 1 of the present invention is provided with a plurality of light projectors 200 that use LEDs as light sources in a planar shape, and a protective cover 300 through which light passes through to cover a plurality of The light guide 200 is fixed to the mounting substrate 400 of one of the plate faces 400a; the heat generated by the plurality of light projectors 20 is radiated, and is protruded from the other plate surface 400b of the mounting substrate 40 0 a plurality of plate-shaped cooling fins 500 fixed to the lower side; and a housing recess 600a having a plurality of plate-shaped cooling fins 500 in the housing recess 600a and a protective cover 300 on the opening surface side of the housing recess 600a The housing 600 of the mounting substrate 400 is fixed. Further, in the same manner as the light projecting device 2 of the illumination lamp 1 described above, the light projector 200 can illuminate the light having directivity emitted from the LED at a wide angle by the lens portion, and in the figure, 32 are 6 columns are arranged in alignment. The casing 600 has an outer shape of the illuminating lamp 100 and has a shape formed by a hollow pyramidal frustum 100a. The open end 6〇〇b of the opening surface of the casing 600 is formed in a rectangular shape. A power supply box 601 is fixed to the upper wall 600c of the casing 600, and the power supply box 601 houses a power supply unit for supplying predetermined electric power to each of the light projectors 2. Further, in the vicinity of the opening end 600b of the side faces 602, 603 which is one of the opposite sides of the casing 60 0, a three-shaped -15-200944710 handle 6〇4 is screwed. Further, a plurality of slits 609 and 610 are respectively pierced and formed on one of the opposite side faces 607 and 608 which are different from the pair of side faces 602 and 601 of the casing 600. The position in which the plurality of slits 609, 610 are provided in the casing 600 is determined by the direction in which the external air rising by the heat dissipation of the plurality of plate-shaped cooling fins 500 is increased in accordance with the direction in which the LEDs of the light projector 200 are irradiated. As described above, by determining the position of the slit, heat released from the plurality of plate-shaped cooling fins 500 can be efficiently released to the outside, so that the cooling efficiency can be improved. Such a case 600 is preferably formed of a metal having a high thermal conductivity such as a magnesium alloy, an aluminum alloy, or copper. However, since the illuminating lamp 100 is lightly sized, it is preferably a magnesium alloy. In particular, in the case of a large-sized illuminator, the ease of grading is more remarkable. Next, a mounting substrate 400 on which a plurality of emitters 200, a protective cover 300, and a plurality of plate-shaped cooling fins 500 are mounted will be described with reference to Figs. 27 to 34. 27 to 34 are views showing a state in which the light projector 200, the protective cover 300, and the plurality of plate-shaped cooling fins 500, which are a part of the components of the illumination lamp of the present invention, are mounted on the mounting substrate 400.

Fig. 32 is a rear elevational view showing a state in which the substrate 400 is mounted when the illumination lamp of the present invention is viewed from the back side. Figure 33 is a cross-sectional view showing a section XX of Figure 27 . Figure 34 is a cross-sectional view showing a section YY of Figure 27 . Further, in Fig. 27 to Fig. 31, since the protective cover 300 is transparent, the light projector 200 is displayed in a solid line. As shown in Fig. 19, the mounting substrate 400 is formed to take in the space φ for taking in the outside air between the inner peripheral walls 600d of the opposite side faces 607 and 608 of the casing 600. The mounting substrate 400 is formed in the vicinity of the opening end 600b of the pair of side faces 602 and 603 of the casing 600, and is fixed to the mounting seats of the pair of side faces 602 and 603 by screws 605 and 606 which are fixed by the three-shaped handle 604. 400c, 400d. By inserting the mounts 400c and 400d into the open end 600b which is the opening surface of the casing 60 0 and screwing the screws 605 and 606 to the pair of side faces 602 and 603, the mounting substrate 400 can be assembled to the casing 600. . As shown in FIGS. 27 to 31, 33, and 34, the protective cover 300 is formed so as to cover a plurality of light projectors 200 along the outer circumference of the mounting substrate 400, and the outer portion is formed to be low in steps, and is fixed by screws or the like. The step portion '301 is fixed to one of the plate faces 400a. This protective cover 3 is formed of, for example, a transparent synthetic resin such as poly-carbonate or acrylic resin. Further, the step portion 301 of the protective cover 300 is covered by the edge cover 3〇2 of the mounting substrate 400. As shown in FIGS. 27 to 34 and 19, the plurality of plate-shaped cooling fins 500 are formed so as to protrude from the space S for taking in the outside air, and are taken out from the space S for taking in the outside air. cool down. Specifically, the plate-shaped cooling fins -17-200944710 500 are formed in a rectangular shape, and when the mounting substrate 400 is assembled to the casing 600, the long direction is fixed to the mounting along a pair of side faces 602, 603 of the casing 600. Substrate 4 00. Further, a plurality of plate-like cooling fins 5 are arranged at equal intervals along a pair of side faces 607, 608 of the casing 600. The space between the plate-like cooling fins 500 is formed to create a space effect in the casing 600. By forming the interval between the plate-like cooling fins 500, the flow rate of the gas passing through the plate-like cooling fins 500 can be increased. The end portions of the plate-shaped cooling fins 500 are formed along a pair of side faces 607, 60 of the casing 600, and the occupied area of the plurality of plate-shaped cooling fins taken into the outer air space S is a bird. The animal cannot enter the size of the housing recess 60 0 0 a of the housing 60 from the opening surface. Since the conventional illuminating lamp has a hermetic structure, animals such as birds do not enter, but the illuminating lamp 100 of the present invention is formed between the mounting substrate 400 and the inner peripheral wall of the casing 600 at 60 d. Since the plurality of plate-shaped cooling fins 500 protrude from the space S for taking in the outside air, the plurality of plate-shaped cooling fins 500 can be taken into the space S for taking in the outside air. An animal whose area is made into a bird or the like cannot enter the housing recess 600a of the casing 600 from the opening surface. Such a plate-shaped cooling fin 500 is preferably made of the same thermal conductive material as the mounting substrate 400. Since the mounting substrate 400 and the plate-like cooling fins 500 are made of the same thermal conductive material, since the thermal conductivity is the same, the heat transfer efficiency is improved. The heat conductive material of the mounting substrate 400 and the plate-shaped cooling fins 500 is preferably formed of a metal having a high thermal conductivity such as a magnesium alloy, an aluminum alloy, or copper, similarly to the case 600, but the illumination lamp 1 is preferably used. 0 0 is lighter and easier to set up, so it is desirable to use magnesium alloy for -18-200944710. The mounting substrate 4 00 in which the plurality of light projectors 200, the protective cover 300, and the plurality of plate-shaped cooling fins 500 are mounted is disposed in a space of about 1/2 of the open end 600b side of the casing 600, and A power supply box 601 is disposed about 1/2 of the remaining space of the housing 600 on the side of the upper wall 600c. In the case where the air flow path for the flow of the outside air flowing into the outdoor air space S as the inflow path is formed in the casing 600, the description will be made regarding the plurality of LEDs. The heat generated by the luminescence spreads to the outside. When the plurality of light projectors 200 are caused to illuminate by illuminating the illumination lamp 100, the heat generated in each of the LEDs is transmitted to the plurality of plate-shaped cooling fins 500 via the mounting substrate 400, since the plurality of plate-shaped cooling fins are removed from the plurality of plate-shaped cooling fins The heat released by the 500 generates a hot updraft, and the outside air is taken in from the space S for taking in the outside air. Since the inhaled outside air passes through a narrow space between the plurality of plate-shaped cooling fins 500, the flow rate of the hot rising gas turbulent flow is increased by the effect of the soil and soil, and is formed into a larger amount than the usual environment. The air passes through a plurality of plate-shaped cooling fins of 500. Further, the outside air which has been heated by the heat dissipation of the plurality of plate-like cooling fins 500 from the space S taken into the outside air space is located, for example, at a plurality of slits 6 0 9 pierced on the side surface 6 0 7 In the case where the plurality of plate-like cooling fins 500 are further above, a larger number of air is released from the plurality of slits 609 to the outside by the hot rising air flow. In this way, since the outside air can be efficiently introduced into the lamp space, and the outside air can be directly guided to the plate-like cooling fins 500, and further escaped to the slit 609, the cooling efficiency can be greatly improved. Therefore, -19-200944710 is ideally suited for high-power LEDs that generate a lot of heat. The present invention has been described with respect to the specific embodiments shown in the drawings. However, the present invention is not limited to the embodiment shown in the drawings, and any structure can be adopted within the range in which the effects of the present invention can be attained. .
